Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Assuming you have zenity installed, and assuming that you keep your backgrounds in ~/backgrounds, then this should work for you! :)

This short snippet outputs the state of all containers available on your system. It is quite helpful to see which ones are running and which are stopped. Please notice that the "sort -u" is needed, otherwise running containers will be reported twice (see output of "lxc-ls" on its own for why)

User: b_t
Functions: readlink xargs

This revision to my command (command #8851) was called for when it failed to find the parent

package of 'rlogin', which is really a deep symbolic link to /usr/bin/ssh.

This revision fixes this newfound issue, while ensuring fixes of other older issues work too.

find . -type f -print0 | xargs -0 rename 's/\ //g'

Functions: find rename xargs

delete file name space

the rename is rename perl version

Sometimes you unzip a file that has no root folder and it spews files all over the place. This will clean up all of those files by deleting them.

grep -rlZ oldstring . | xargs -0 sed -i -e 's/oldstring/newstring/'

Functions: grep sed xargs

Using -Z with grep and -0 with xargs handles file names with spaces and special characters.

calls grep on all non-binary files returned by find on its current working directory

for each in /usr/bin/*; do echo $each | sed 's/\/usr\/bin\///' | xargs touch; done

Functions: echo sed xargs

This will make a false directory with the same file names as whatever directory you choose. This is wise to use when testing scripts that alter contents, filenames, or move files. I wrote this after an OOPS I made when renaming a directory of JPGs, PNGs, PSDs that were mixed. I recommend this as I lost over 2000 vacation pictures and some graphics I designed for software and web sites. :(

NOTE: This only creates name copies, that data itself is not copied.

Helps if you accidentally deleted files from an svn repo with plain rm and you would like to mark them for svn to delete too.

LC_ALL=C diff -q dir1 dir2 | grep differ | awk '{ print $2, $4 }' | xargs -n 2 gvim --nofork -d

User: brock
Functions: awk diff grep xargs

LC_ALL=C is here to always grep on "differ" whatever your language env.

xargs -n 2 to run gvim -d with 2 arguments

gvim --nofork to use only one instance of gvim

find . -type f | xargs grep -n "Old Text" | tee filesChanged.txt | sed 's/:.*$//' | xargs sed -i 's/Old Text/New Text/g
find -iname \*.pdf -print0 | xargs -0 pdfgrep -i "my search text"

This works more reliable for me ("cut -c 8-" had one more space, so it did not work)

find . -type f | xargs grep -l "string"
2011-08-30 13:22:42
User: Neo23x0
Functions: find grep xargs

Finds a string in files recursively below the current directory on systems without the "egrep" and its "-r" functionality.

grep -lr -e '<oldword>' * | xargs sed -i 's/<oldword>/<newword>/g'
2011-08-27 02:42:51
User: o0110o
Functions: grep sed xargs

- grep for the word in a files, use recursion (to find files in sub directories), and list only file matches

-| xargs passes the results from the grep command to sed

-sed -i uses a regular expression (regex) to evaluate the change: s (search) / search word / target word / g (global replace)

find . -iname '*.conf' | xargs grep "searh string" -sl
allVideos() { find ./ -type f -print0 | xargs -0 file -iNf - | grep ": video/" | cut -d: -f1; }

Functions: cut file find grep xargs

Videos are found using their MIME type. Thus no need to for an extension for the video file.

This is a efficent version of "jnash" cmd (4086). Thanks for jnash. This cmd will only show video files while his cmd show files having "video" anywhere in path.

Doesn't use shuf, its much faster with "shuf -n4" instead of sort -R

Functions: find ls sort xargs

Tells you everything you could ever want to know about all files and subdirectories. Great for package creators. Totally secure too.

On my Slackware box, this gets set upon login:

LS_OPTIONS='-F -b -T 0 --color=auto'


alias ls='/bin/ls $LS_OPTIONS'

which works great.
